Here's The Unforgettable Moment When Obama Realized He Had Forgotten To Salute A Marine

Obama recently forgot
to salute a Marine on his way into the Marine One helicopter,
promptly turned around and went back to shake the Marine's hand.

You can clearly see the Marine smile and say "Thank you, Sir."

President Ronald Reagan started the presidential salute to
Marines in 1981 when he asked Gen. Robert Barrow,
then-commandant of the Marines, if he could salute the Marines
working around the White House.

Barrow responded with what now seems pretty obvious, "Sir, you
can salute whomever you want,"
according to Carey Winfrey, former Marine and former editor
of Smithsonian Magazine.
